Several observers studied the two kingbirds at Cobb SWA in Wellington this morning. The more yellow one was confirmed as Cassin’s by vocalization, as it gave the familiar “cheweer” several times. The other mystery Kingbird stayed close to the Cassin’s, often interacting and perched in the same bush. It vocalized once (unrecognized) but was not recorded.
In Cyberspace, there is a healthy discussion of possibilities by many experts in the ID Frontiers listserve. Consensus is building toward a hybrid combo of some sort. I’ve attached a photo taken this morning. My money is on Thick-billed x Cassin’s, but I usually lose when I gamble. 😎

Their identity is being discussed and debated by experts. One may indeed be a Cassin’s Kingbird, an expected migrant in this date. The other remains a mystery. To reach the location, drive north a half mile on CR3 from CR56 and park in the designated area. Hike west to the shelter belt. Observers who are able should record any vocalizations and include them on your eBird checklist.
